Title: The Innovative Contributions of Robert Kitchel Earl
Introduction
Robert Kitchel Earl is a notable inventor based in Carmel, IN (US). He has made significant contributions to the field of electrochemical biosensors, holding a total of 4 patents. His work focuses on enhancing the functionality and user experience of test strips used in various applications.
Latest Patents
One of Robert's latest inventions is an electrochemical biosensor test strip that incorporates four innovative features. This test strip includes an indentation that provides a tactile feel for the location of the sample application port. The sample application port leads to a capillary test chamber containing a test reagent. The wet reagent consists of 0.2% to 2% by weight polyethylene oxide, with a mean molecular weight ranging from 100 kilodaltons to 900 kilodaltons. This formulation enhances the hydrophilicity and durability of the dried reagent, making it more resilient during processing steps such as mechanical punching and user manipulation. Additionally, the roof of the capillary test chamber features a transparent or translucent window that serves as a "fill to here" line, indicating when an adequate liquid sample, such as blood, has been added for accurate testing. Furthermore, the test strip may include a notch at the sample application port to mitigate a phenomenon known as "dose hesitation."
